First Canadian Case of Moraxella Osloensis Meningitis
Bibliographic record
Abstract
Moraxella osloensis is a rare cause of bacterial meningitis. There have been eight total reported cases of M. osloensis meningitis to date. We describe a unique case of a 53-year-old male with a history of extensive sinusitis who presented twice with M. osloensis meningitis. The first presentation of meningitis was a fever, headache, and neck stiffness. Upon the second presentation five months later, he had a fever, headache, neck stiffness as well as an altered level of consciousness. He underwent several investigations, including blood work, lumbar puncture, and imaging both times; however, on the second presentation, he had a CT scan of his sinuses, where bony destruction of the cribriform plate, which provided sinus communication to the CSF, contributing to his second presentation of meningitis. This case highlights the consideration of M. osloensis as a causative agent of meningitis in immunocompetent patients in Canada.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
